How to Add a Watermark to a PDF
A watermark is a piece of text or an image laid over the content of every page — think "DRAFT", "CONFIDENTIAL", or a company logo sitting faintly behind the text. It is one of the quickest ways to signal a document's status or ownership without altering the underlying content.
What watermarks are good for
- Marking drafts so an unfinished version is never mistaken for final.
- Asserting ownership by stamping a logo or business name across each page.
- Flagging confidentiality to discourage casual sharing.
- Discouraging reuse of proofs, samples, or preview copies.
Text or image?
A text watermark is fast and flexible: type a word, choose its angle, size, and transparency, and you are done. Diagonal, semi-transparent text across the centre of the page is the most recognisable style.
An image watermark uses a logo or graphic. Keep it light — a watermark should sit behind the content, not fight with it. Lowering the opacity so the text underneath stays comfortably readable is the key to a professional result.
How to add one
- Open the Watermark PDF tool and upload your document.
- Enter your text or upload a logo image.
- Adjust position, rotation, and transparency.
- Click Process and download the watermarked file.
Before you distribute
If the watermarked document is going out for review, it is a good moment to also add page numbers or to protect the file with a password so only intended recipients can open it.
